My mom was having an issue with her D11-500. The issue was that the receiver, when it changes channels, does not display picture until about two to three seconds after the channel has been changed. Audio, however, is immediately changed when the channel changes. I called in to DirecTV and got it replaced with a D12-100. The D12-100 is doing the exact same thing, immediately after activation. I thought it was something along the lines of software needing to be updated, so on both receivers - I forced a software download. My mom has a 32" Philips Plasma connected with composite cables. I used the composite cables that came with the new receiver, because I figured it might be something as simple as changing the cables. At the time that I was troubleshooting with the agent, I did not actually have the cables available to swap them out. The problem that I am running into, is that I have an LG Plasma, a D12-500, and I am using composite cables, too. I have no problem changing channels and having immediate video and audio. Both televisions are HDTVs and I have them both set to auto detect the aspect ratio and convert the picture to fit the screen size for the televisions. So the picture I am getting fills the screen and does not have the bars on top. How is my television/receiver combination able to automatically detect video and audio after channel changes, and my mom's television/receiver combinations unable to do so? Any answers/suggestions/comments are appreciated.
